data definitions
MD 35020: SPIND_DEFAULT_MODE (spindle initial setting)
This MD allows a spindle initial setting to be defined.
The following are possible:

The time at which the spindle initial setting acts is defined by means of MD
35030: SPIND_DEFAULT_ACT_MASK.
The following are possible:
S
S
S
MD 35040: SPIND_ACTIVE_AFTER_RESET (independent spindle reset)
This MD determines whether the spindle must be stopped by a RESET or a
program end. If the MD has been set, a termination of the spindle functions
must be initiated explicitly via a program command or the IS "Spindle reset"
(DB31, ... DBX2.2).
MD 35010: GEAR_STEP_CHANGE_ENABLE (gear stage changeover
possible. Spindle has several gear stages).
If this machine data is not set, the system assumes that the spindle has no gear
stages. A gear stage changeover is therefore impossible.
Parameter sets
With the following machine data and the field parameter "Gear stage no." and
"Control parameter set no." the selected gear stage determines the appropriate
field index. The field with index "0" is not used for the spindle machine data!
(See above in this chapter in the "Axis data" section.)

MD 36200: AX_VELO_LIMIT (threshold value for speed monitoring)
Example
MD 35110: GEAR_STEP_MAX_VELO [0,A1] = 500 (not used for spindle)
MD 35110: GEAR_STEP_MAX_VELO [1,A1] = 500
MD 35110: GEAR_STEP_MAX_VELO [2,A1] = 1000
